Marileidy Paulino stamped her authority as the best female 400m runner in the world for 2023 when she destroyed a talented field to win the one-lap sprint at the Diamond League finale in Eugene, Oregon on Sunday.

The 2023 world champion ran a fast 49.58s to add the Diamond League trophy to her world championship gold medal in what has been an incredible season in which she lost only once all year.

Paulino was almost a second clear of the fast-improving Polish athlete Natalia Kaczmarek, who clocked 50.38 for second place. Lieke Klaver of the Netherlands was not far behind in 50.47.

Jamaica’s Candice McLeod, who looked good for a podium finish after 300m faded to fourth in 50.76 with world championship bronze medallist Sada Williams of Barbados clocking 51.07 for fifth. Aliyah Abrams of Guyana was eighth in 51.97.

Cynthia Bolingo stormed past a talented field to win the 400m at the Diamond League meeting in Brussels on Friday. Candice McLeod was among those who she zipped past down the home stretch, the Jamaican finishing in fifth in 50.82.

Lieke Klaver of the Netherlands and Shamier Little of the USA, as well as McLeod, battled for the lead over the first 300m with the American taking the lead coming off the curve into the home straight. She seemed headed for victory before Bolingo unleashed a stirring run to take victory in 50.02.

Klaver managed to edge ahead of Little to take second place in 50.16 with the American fading to third in 50.58.

Great Britain’s Victoria Ohurugou managed to out-lean McLeod at the line to take fourth in 50.81.
